The scumbag brother somehow got a nice redemption but about the noble couple? Do they see Anna again, do they apologize? I just cannot understand use such a heavy setup if you don't want to develop properly the obvious emotional scarring everyone should have lol
From what I got from the google translated raws, they never meet again. And the brother's redemption really seemed out of nowhere, last we heard from him he refused to consider MC his sister, and then at the end they had a friendly relationship again, and MC says he "always helped her secretly".
